Sagot :

QUADRATIC EQUATION

Direction: Determine the discriminant of x²-12=0 and the nature of roots.

Final Answer:

  • Discriminant: 48
  • Nature of roots: Real, irrational, and unequal

Step-by-step explanation:

x² - 12 = 0

First, identify the value of a, b, and c.

Given:

  • a = 1
  • b = 0
  • c = -12

Second, write the formula.

Formula to be used: [tex]\: \bold{ {b}^{2} - 4ac}[/tex]

Lastly, solve using the formula then identify its nature of roots.

[tex]\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered} {b}^{2} - 4ac \\ {(0)}^{2} - 4(1)(-12) \\ 0 + 48 \\ 48 \end{gathered} \end{gathered} \end{gathered} \end{gathered} [/tex]

Thus, the discriminant is 48 and the nature of roots is real, irrational, and unequal.
